Two mononuclear Tc complexes: [2,2′-(3-phenylpropylimino)- and [2,2′-(propylimino)-bis(ethanethiolato)](4-methoxybenzenethiolato)-oxidotechnetate(V)

The molecular structures of the two mononuclear title complexes, namely (4-methoxybenzene-thiolato-κS)oxido-[2.2′-(3-phenylpropylimino)bis(ethanethiolato)-κ³S,N,S′]technetium(V), [Tc(C₁₄H₂₁NS₂)(C₇H₇OS)O], (I), and (4-methoxybenzenethiolato- κS)oxido[2, 2′-(propylimino)-bis(ethanethiolato) -κ³S,N,S′]technetium(V) [Tc(C₇H₁₅NS₂)(C₇H₇OS)O], (II), exhibit the same coordination environment for the central Tc atoms. The atoms are five-coordinated (TcNOS3) with a square-pyramidal geometry comprising a tridentate 2.2′-(3-phenylpropylimino)bis(ethanethiolate) or 2, 2′-(propylimino)-bis(ethanethiolate) ligand, a 4-methoxybenzenethiolate ligand and an additional oxide O atom. Intermolecular C–H …O and C–H...S hydrogen bonds between the monomeric units result in two-dimensional layers with a parallel arrangement.
